Question

我有一个简单的应用程序，其热线模型是一个mongoid文档。创建和视图工作正常但编辑我似乎无法为我的生活工作。

我希望有人能帮我辨别我做错了什么。

这是我正确运作的创建形式：

  <%= form_for Hotline.new, :url => {:action => "create"} do |f| %>
    <div class="row top-buffer">
      <div class="form-group">
        <label class="col-sm-1 rt-label" for="textinput">Address</label>
        <div class="col-sm-3">
          <%= f.text_field :city, class: 'form-control input-sm', placeholder: "City" %>
        </div>
        <label class="col-sm-1" for="textinput"></label>
        <div class="col-sm-3">
          <%= f.text_field :zip, class: 'form-control input-sm', placeholder: "Zip" %>
        </div>
      </div>
    </div>
    <br>
    <div class="form-group">
      <label class="col-sm-1" for="textinput"></label>
      <%= f.submit "Save", class: 'btn btn-sm btn-success' %>
    </div>
  <% end %>

我尝试更改网址以便在我的编辑表单中发布或创建并使用h ...但它一直没有给我路由匹配错误。

No route matches {:action=>"patch", :controller=>"hotlines", :person_id=>"2"}

以下是包含视图和put或patch作为操作的表单：

<% @hotlines.each do |h| %>
  <div id="log" class="visable">
    <p>View Log</p>
    <%= "City: " + h.city %><br>
    <%= "Zip: " + h.zip %><br>
  </div>
  <br>
    <div id="edit" class="visable">
      <p>Edit Log</p>


  <%= form_for h, :url => {:action => "patch"} do |f| %>
    <div class="row top-buffer">
      <div class="form-group">
        <label class="col-sm-1 rt-label" for="textinput">Address</label>
        <div class="col-sm-3">
          <%= f.text_field :city, class: 'form-control input-sm', placeholder: "City" %>
        </div>
        <label class="col-sm-1" for="textinput"></label>
        <div class="col-sm-3">
          <%= f.text_field :zip, class: 'form-control input-sm', placeholder: "Zip" %>
        </div>
      </div>
    </div>
    <br>
    <div class="form-group">
      <label class="col-sm-1" for="textinput"></label>
      <%= f.submit "Save", class: 'btn btn-sm btn-success' %>
    </div>
  <% end %> 


  </div>


  <% end %>

不确定是否需要，但我的代码中还有一些内容。

控制器（我意识到更新不完整但我似乎无法进行渲染编辑）

class HotlinesController < ApplicationController
  def index
    @person = Person.find(params['person_id'])
    #binding.pry
    #@person = Person.find(params: id)
    #@hotlines = Hotline.where(person_id: @person.id)
    @hotlines = Hotline.where(person_id: params['person_id'])
  end

  def new
    @new_hotline = Hotline.new
  end  

  def create
    @new_hotline = Hotline.new(hotline_params)
    @new_hotline.person_id = params['person_id']
    if @new_hotline.save
      redirect_to person_hotlines_path(params['person_id']), notice: "Hotline was added successfully."
    else
      flash[:error] = "Error creating hotline. Please try again."
      render :new
    end
  end

  def update
    @person = Person.find(params['person_id'])
    @update_hotline = Hotline.find(params[:id])
     if @update_hotline.update_attributes(person_params)
       redirect_to person_hotlines_path(params['person_id']), notice: "Person was updated successfully."
     else
       flash[:error] = "Error saving person. Please try again."
       render :edit
     end  
  end

  private

  def hotline_params
    params.require(:hotline).permit(:person_id, :city, :zip)
  end    
end

路线

  devise_for :users
  resources :users, only: [:update, :index, :new, :edit, :create] 
  resources :dashboard, only: [:index]
  resources :people do
    resources :hotlines, only: [:index, :create, :update, :new]
  end

  post 'dashboard/search'
  get '/person/:id', to: 'person#show'
  get 'welcome/index'
  get 'welcome/about'

  root to: 'welcome#index'

您的更新网址问题与没有名称＆＃34; patch＆＃34;的行动和路线有关。请将其更新为：

<%= form_for h, :url => {:action => "update", :method => :put } do |f| %>

或使用命名路线。此控制台命令将帮助您使用可用路径：

"rake routes | grep user"

然后编辑表单变为：

<%= form_for h, :url => user_path(h) do |f| %>

希望它有所帮助。

Ruby中的Mongoid编辑表单不起作用
